Some Reasoning: a) Even if all information about every person is publicly accessible, none of us will know everything about all of us (Us being humanity). Some things about some people would be known by more people. For example, more people would know that the president is the president than whether I got a haircut any given day. Indeed, more people would know that the president exists than would know that I exist. There is a limited amount of attention, and not enough to give attention to everything, so some things must have more attention on them than others. b) Negative attention can harm someone. Harassment hurts. c) having information about someone can make it easier to focus the attention of others on that person, including negative attention. This is true even when the people whose attention is in question already could have accessed the information beforehand, but haven't. Perhaps even especially true. Conclusion) Having all information available about all persons makes it easier for those who can direct people's attention to direct negative attention against those who they wish to do so against, and therefore increases their ability to harm those people, and therefore increases their power over them. So a total lack of privacy makes those with power over attention more powerful.
